Deputies said the most recent aggravated sexual assault occurred about 3:15 a.m. Sunday in the 1100 block of S. Seventh. A 22-year-old woman told investigators a man approached her and asked her for a cigarette. Then he asked to use the bathroom in her apartment. Inside the apartment, the man threatened the victim and sexually assaulted her. He stole the woman's vehicle and other personal items. The vehicle was later found.

Deputies said the other attack occurred about 9 p.m. Saturday in the 900 block of Bellshire. A 22-year-old woman told investigators a man approached her and asked to borrow her cellular phone. Then the suspect sexually assaulted her. The woman escaped and ran away to find help.

The suspect left after the victim escaped.

Police said the victims' description of the attacker and other information led investigators to consider Mitchell to be a suspect in the cases. Investigators did not reveal what other information suggested Mitchell was the suspect.

Mitchell is being held in the Montgomery County Jail in lieu of $200,000 bail.
